A ribbon-cutting ceremony with Endeavour commander George Zamka and station commander Jeff Williams to celebrate the arrival of Tranquility and its seven-windowed cupola on the International Space Station includes the placement on permanent display in the node of a rock brought back from the moon's Tranquility Base by Apollo 11 astronauts Neil Armstrong and Buzz Aldrin in 1969, and carried by shuttle astronaut Scott Parazynski to the summit of Mt. Everest in 2009
